If you are an iOS developer
If you are an iOS developer then the links I pointed out below would be the best starting point along with the approach.
In fact probably the best thing is to prototype the whole thing without Vuforia in the first instance so you can understand the flow and develop the key classes and interface.
Unfortunately we are not in the position where we can write apps for developers, because our primary purpose is to help support Vuforia, so you may need to look elsewhere or maybe hire someone that can do this for you.
Hope you can understand :)

Yes i mean using touch
The Blippar solution you
The Blippar solution you refer to in the video is simply using touch against an image on the screen, not Virtual Buttons which is where the user touches in front of the camera.
In the video the augmentation appears made up of 6 tiles, and these are simply images that the user can touch on screen, and these can easily be detected within iOS natively or within Unity.
So the approach you will need to take is to develop a class called something like "TouchableAugmentationButton" which contains the image you want to display and which is capable of handling touches. These links make help you.

Once you have these then you will need to have your code display them as images that are augmented to the display. This will be much easier in Unity as anything that is a child of the ImageTarget will automaticaly get enabled, along with any behaviour that is part of an attached script.

Currently the examples do not
Currently the examples do not show combining Virtual Buttons with CloudReco and I am not sure whether anybody has tried it.
Probably the best thing to do is to prototype this with a device database using the Virtual Buttons example as a starting point - and most likely you will make quicker progress if you are able to do this in Unity.
However the problem you may run into is that as the user moves their finger across the grid you have shown, they might press the wrong button by moving their finger across - so best to test out the feasibility before you spend too much time :)
